Ahead of schedule all excavation of job site is complete. Cannot imagine a 4 block site up to 80 ft deep how much material was removed. Note the below announcement also says all steel bracing is installed. The area of the terminal is in an area that the soil is not stable. Anyone know ?
Here is announcement -----------
The Transbay Joint Powers Authority has officially reached another substantial milestone: the completion of excavation and internal bracing of the 4 block jobsite! Although excavation is complete, there are other important activities ahead of us such as the completion and testing of micropiles and geothermal piping, installation of waterproofing, and the continued foundation work as we progress into the Eastern Transit Center site. Steel fabrication is underway and will be assembled onsite this summer! Join us on Wednesday, February 19, 2014 to learn more about these activities and what's in store for us in the coming year. The community meeting will be held at 12 noon at the TJPA offices located at 201 Mission Street, Suite 2100. We appreciate that you are taking your lunch hour to learn about this innovative project, and would of course welcome you to bring food or drinks to this meeting.
